The invention relates to a cotton fabric antibacterial finishing agent and a preparation method thereof. The cotton fabric antibacterial finishing agent is prepared from the following raw materials in percentage by weight: 1.0-2.0% of an antibacterial agent, 1.0-2.0% of a cross-linking agent, 0.5-1.0% of a penetrating agent and the balance of water, wherein the antibacterial agent contains a biquaternary ammonium salt symmetric compound with a hydroxyl group. The antibacterial finishing agent for the cotton fabric has good antibacterial performance, and the cotton fabric can have efficient and broad-spectrum antibacterial performance and good washing resistance. When the antibacterial finishing agent is used for dipping and baking the cotton fabric, the antibacterial rate of the fabric on escherichia coli and staphylococcus aureus is 99% or above, and the antibacterial rate of the fabric washed for 30 times can still reach 90% or above. And the antibacterial finishing agent is simple in ...

Принадлежит:

The invention relates to a sodium hydrogen persulfate composite salt substrate modifier for aquaculture and a preparation method of the sodium hydrogen persulfate composite salt substrate modifier. The substrate modifier comprises the following components in parts by mass: 40-55 parts of sodium hydrogen persulfate composite salt, 5-10 parts of organic acid, 1-5 parts of a stabilizer, 20-50 parts of an adsorption filler, 2-5 parts of a surfactant and 2-8 parts of a flocculant. According to the invention, the sodium hydrogen persulfate composite salt is used as a main component of the water substrate modifier, has strong oxidizing property, can release active oxygen, free radicals and other derivatives after being contacted with aquatic water, and can efficiently oxidize and decompose organic matters and hydrogen sulfide, nitrite, ferrous iron and other reducing substances through chain reaction, thereby reducing the odor and enhancing the water quality. The effects of increasing the dissolved ...

Method for treating emulsifier peregal in terpineol production through ceramic ultrafiltration membrane

Номер: CN103566761A
Автор: FU ZUXIAN
Принадлежит:

The invention discloses a method for removing an emulsifier peregal in terpineol production through an alumina ceramic ultrafiltration membrane. The method comprises the following steps: removing the emulsifier peregal in the terpineol production through a nanometer ceramic ultrafiltration membrane to avoid severe bubbling in the discharged acidic wastewater due to over high concentration of the emulsifier peregal to affect the normal operation of a sewage treatment system.
